Fascia boards, soffits and bargeboards form the roofline of your property — they support guttering, seal the roof void, and provide essential ventilation. When they rot, warp or crack, water gets into Serving Harrow and all surrounding areas in Harrow.
Fascia boards, soffits and bargeboards form the roofline of your property — they support guttering, seal the roof void, and provide essential ventilation. When they rot, warp or crack, water gets into the roof space and your guttering loses its support. We strip failed roofline back to sound timber and install new fascia, soffit and bargeboard in uPVC or treated timber.
Peeling paint, soft or spongy boards, visible gaps between fascia and wall, wasp or bird nests in the soffit, sagging gutters — these all indicate roofline failure. In Harrow, the most common cause is decades of blocked gutters driving water into fascia boards.
uPVC is maintenance-free, rot-proof and available in a range of colours. Timber gives a traditional appearance and is required in some conservation areas. For most Harrow properties, uPVC is the practical choice — it eliminates the repainting cycle and lasts 20-30 years.
Adequate roof void ventilation prevents condensation that rots timbers from the inside. We install ventilated soffits as standard on every roofline replacement in Harrow — continuous soffit vent strip provides the 10mm equivalent ventilation gap required by Building Regulations.
The hilltop conservation area around Harrow School has listed buildings with original Welsh slate and handmade clay tile roofs. Below the hill, 1920s-30s Metroland semis fill the streets around Harrow-on-the-Hill station. Wealdstone to the north has Victorian terraces and post-war estates. For fascia & soffits work in Harrow, this housing profile means we commonly encounter Wind exposure on hilltop properties is severe — ridge tiles and mortar joints fail at double the rate of sheltered lowland properties. Conservation area restrictions on the Hill mean only approved mat
The streets of Harrow — including High Street Harrow on the Hill, Station Road Harrow, Kenton Road — have roofing characteristics that reflect their construction era and the specific exposure conditions of Harrow. Harrow's elevated position means roofs here face wind loading that properties in the Thames valley floor simply do not experience. Harrow on the Hill is fully exposed to south-westerly gales — wind sp

Quality uPVC fascia boards last 20-30 years with no maintenance. Cheaper products may discolour or warp within 10-15 years. We use only established manufacturer products with a minimum 10-year colour guarantee.
Technically yes, but we strongly recommend replacing guttering at the same time. The scaffold is already up, and old gutter fixings often damage new fascia boards during reinstallation.
Not in most cases. However, if your Harrow property is in a conservation area, you may need to match existing materials and profiles. We advise on planning requirements as part of our quotation.
The primary cause is blocked or leaking gutters — water overflows onto the fascia board and soaks in over time. Once rot starts, it spreads along the grain and eventually compromises the gutter mounting points.
If the boards are sound with only surface weathering, painting can extend their life by 5-10 years. If there is any rot, softness, or warping, replacement is the only effective solution.
Yes — ventilated soffit strips are included as standard on every roofline replacement. This provides essential roof void ventilation that prevents condensation and timber rot.
Harrow's hilltop position has shaped its roofing history for centuries. Harrow School, founded in 1572, sits atop one of London's highest points at 124 metres — and the roofs of its listed buildings have withstood four centuries of some of the most aggressive weather exposure in Greater London. The conservation area around the Hill contains Grade II listed buildings where original Welsh slate and handmade clay tile roofs demand specialist maintenance using period-appropriate materials and techniques.
Wind is Harrow's defining roofing challenge. Harrow-on-the-Hill is exposed to south-westerly gales that drive rain horizontally into mortar joints, accelerate lead fatigue through constant flexing, and create uplift forces on ridge tiles that sheltered locations simply do not experience. Weather station data consistently shows wind speeds 15-20% higher on the Hill than at equivalent lowland sites. This is not a marginal difference — it translates directly into mortar joints failing twice as fast and ridge tiles needing re-bedding twice as frequently.
Pinner's conservation area and village character drive property premiums that make roof maintenance an investment priority. Tudor and period properties on Pinner High Street and the surrounding conservation area require specialist roofing skills — lime mortar repointing, handmade peg tile sourcing, and lead detailing that matches the original specification. These are not jobs for general builders.
Every job follows our standard quality process: free inspection and assessment, written quote with full scope of work, professional installation by our own team using specified materials, post-completion inspection with photographic record, and a written guarantee. This process applies to every job regardless of size — a £200 repair gets the same professional approach as a £15,000 re-roof.
We specify materials based on the specific conditions of your property — its age, construction type, exposure and the performance requirements of the job. We never use the cheapest available option as default — we use the right option for your situation and explain why. All materials are sourced from established manufacturers with proven track records.
All work carries our written workmanship guarantee. The guarantee period depends on the scope of work — from 2 years on minor repairs to 10 years on full installations. Guarantees are transferable if you sell the property. Materials carry the manufacturer's own guarantee in addition to our workmanship cover.
No call-out fees. No obligation. Just an honest quote from a local Harrow roofer who turns up when they say they will.
